METHOD OF COLORING ARN ON BOBB'INS.

Application filed November 20, 1924. Serial No. 751,089.

r1`hisinvention relates to a metho'd of colorinpr yarn on the bobhin the object being to producen uniform coloringrot .a portion ol' the yarnl'rom the periphery to the core, leaving the remaining portionsunt-olored.

(hie oi the specific objects is to provide a more exfliedtious method ot' carrying out the preceding object than has heretofore been practiced.

(lher objects and uses will be broughtiout in (he t'ollo\\'ixif.r descriptions.

in the dra\\'ings:-

Figure l is a face View of a hobhin ot" yarn showingr the colored portion thereof by a circumferentially extending hand of relatively dark lines.

Figure 2 is an enlarged longitudinal Sectional view ol' the bohbin and portions ot the apparatus used in carrying out the coloring process.

Figure 3 is a transverse sectional view through the bobhin, core and suction nozzle Showing' also the delivery nozzle for the coloring matter.

In carrying out this process a perforated core -1- carrying a mass of yarn -2- wound thereon is placed over and upon a suction nozzle -3'-` which may be connected to any suitable suction producing device not necessary to herein illustrate or describe. This nozzle is tnet'erahly tapered and is provided with radial perforations 4 through the walls thcremc and adapted to register with similar peri'orations 5 in the walls oi' the hollow core --l when the latter with the yarn wound thereon is placed on the suction nozzle.

A, delivery nozzle Q for t-he coloring liquid mayv be connected to any source of supply prefcrablyin such mannerv as to enable the liquid to lowhy gravity to the nozzle, the mouth of which is arranged in close proximity to the periphery of the mass of yarn -2-.

The nozzle -2* forms a part of a man-V,

drel which is adapted to be rotated by any suitable means to etieet a corresponding rotary movement of the core 1 With the bobhin thereon when the core is frictionally engaged with the tapered nozzle.

For example, when the ocre .-1- With the yarn wound thereon is ,placed upon the suction nozzle -3- and rotated thereby, the coloring fluid is allowed to flow into the nozzie and against a portion of the peripheryl of the yarn -Q- and at the saine time suctionis producedvin vthe vnoz/,zie -3- to draw the coloring fluid from the mouth of its nozzle through the interposed portion ol the yarn as the bobbin with the vyarn thereon is rotate/l relativclypto the delivery This rotation causes a distribution of the coloring luid cireumi'ercntially around the periphery oi' the yarn during;r which rotation the suction through the porous yarn causes the coloring fluid to be drawn along direct,y hues e-av, Figures 2 and 2l,- between the tures in the suction nozzle.

lhe portion of the suctonnozzle adjacent the apertures in the core -1 is provided with a peripheral `groove -7- of suiiieient length lo assure its registration with the apertures -5 when the core with the yarn wound thereon is placed upon the nozzle, the object ot' the annular I {roove -i'- being to assure communication between the apertures mouth of the delivery nozzle -(S- and aperin the nozzle. and those in the core in case the apertures ot' one of those parts should not register with those of the other part, thereby maintaining ehmmnnication between the interior ot the suction nozzle and de;

livery end of the supply nozzie ior the l coloringr matter through the porous yarn.

The tace width of the delivery nozzle -6 is, of course, considerably less than the length of the hobbin to assure the coloring of a portion only ot' the yarn alongl the lines of suction between the apertures -4- and nozzle -(i-, leaving;r the remaining yportions oi the yarn uncolored.

This method of coloringr portions ot' the yarn is found in actual pl'zwticefto be verv expeditious and ccononcal by reason ot the tact that the yarn is colored in mass or on the bobhin without unwinding itthererom, thereby producingr a more even distribution of the coloring liquid in the colored portions of the yarn so that when it is knitted into fabric the colored portions blend with the uncolored portions and impartl the dcsired cloudy or mottled appearance. l

For further descriptionof the details ot' the construction of the apparatus, reference may be had to pending application Serial No` 751,07() filed November 20, 1924.

lVhat lr claim is:-

1. The herein described process for coloring portions of'yarn on the bobhin consisting in applying a coloring'luid to `a portion of the periphery of the yarn on the bobbin and drawing Said coloring matter into the yarn by suction applied to the interior of the bobbin.

2. The herein described method of colorvits axis, creating e current of air through a limited portion of the mass from one surface to the other und introducing coloring fluid into the Current of -nir .as it passes through the mass.

4. The herein desembod nietlfodfof color-l ing u hollow mass of yarn having inner and outer surfaces consisting in applying.)Y suction to u port-ion of one of said surfaces yand simultaneously applying the coloring matter to a portion of the other surface and simultaneously rotatinr said muss.

5. The herein descri ed method of coloring a muss of yarn consisting in applying nozzles to the interior and to the exterior of the mass .ot' yarn, producing suction in one of the. nozzles and supplying `coloring,r matter through the other nozzle.-

6. The herein described .method ot coloring u muss of yarn Consisting in applying nozzleslo the interior and to the exterior of the uniss of yurn, producing;r suction in one of the nozzles und supplying; coloring matter through thc other nozzle und rotating the yarn relatively to one of the nozzles.

In witness whereof l. hure hereunto Set my hund this 5th duy of November, 1924.
